Uyenza njani inkqubo yokucoca engcono?

Kwentliziyo ye Ukuqhuba I-Fume Hood, indawo yokusebenzela okanye i-enclosure yinkqubo yokucoca isigaba segesi esakhiwe ngezihluzi zangaphambili kunye nekhabhoni ephambili kunye / okanye i-HEPA filters. Izihluzi zangaphambili zifakwe kwiindawo zokungena kuzo zonke iinkqubo zokuhluza ukususa izinto ezinzulu ukusuka kumjelo womoya kunye nokuthintela ukuvaleka kokucoca okungundoqo. Izihluzi eziphambili zinokuba ngumaleko omnye wohlobo olunye, iileya ezi-2 zohlobo olunye okanye iileya ezimbini zeentlobo ezimbini zezihluzo zekhabhoni ezisebenzayo kunye nezihluzo zeHEPA. Izihluzi zekhabhoni zezona ntlobo zidumileyo ezifakwe kwiihoods zomsi ezingenambhobho kunye nezibiyelweyo zokususa imichiza ekuhambeni komoya, ngelixa izihluzi ze-HEPA zisetyenziswa kwizicelo kunye ne-particulate okanye i-aerosol ekufuneka ibanjwe nayo.

1. Ukuhluzwa kwangaphambili

Isihluzi sangaphambili sisihluzo sefayibha etshajiweyo nge-electrostatically esusa ngokufanelekileyo ii-submicron particulates. I-Prefilter ikhusela ezona zihluzo ze-adsorption eziphambili, ikhabhoni kunye/okanye i-HEPA, kumsi, inkungu ye-asidi kunye nezinye iincinci ze-micron.

2. UkuHlungwa kweKhabhoni eBond

Xunling yenza izihluzi zegesi ezibotshelelwe kwikhabhoni ezifumaneka kusetyenziswa iqokobhe lekhokhonathi esemgangathweni ikhabhoni okanye ikhabhoni efakwe imichiza yokwandisa umthamo womthwalo. Xa kuthelekiswa nezihluzi zekhabhoni zegranular ngokupheleleyo ezinokusasazwa ngokungalinganiyo kunye neenduli kunye neentlambo kwikhabhoni kwaye zikhokelela kwiindawo zokuphumela kunye nokuvuza kothuli, izihluzi zethu ezidityanisiweyo zekhabhoni ezizodwa zineengenelo ezingenakulinganiswa. Inkqubo yethu yobunini bokubambisana ibamba ikhabhoni kwi-matrix eqikelelwayo, ukuthintela ukutshintshwa kwekhabhoni okungakhokelela "kwiendawo ezifileyo" eziqhelekileyo kwizihluzi zegranular zemveli.

Ikhabhoni yethu esebenzayo ifakwe kwizongezo zekhemikhali ezikhethekileyo, iyenza ibe namandla aphezulu kwiikhompawundi ezingabhengezwanga ngamandla yikhabhoni ngokubanzi, njengehydrogen sulfide, imercaptans, sulfur dioxide, chlorine, hydrogen chloride, nitrogen oxides, formaldehyde kunye neammonia.

3. I-HEPA/ULPA Filtration

I-HEPA (i-High Efficiency Particulate Air) kunye ne-ULPA (i-Ultra Low Penetration Air) izihlungi zezona ntlobo zidumileyo zokuhlukanisa i-aerosol kunye ne-particulate kwizicelo ezininzi, ngakumbi kumashishini amayeza, izibhedlele, izityalo ze-chemistry emihle, i-CDC kunye ne-laboratories ye-forensic. Izihluzi ze-HEPA zingasetyenziselwa ukuqulatha i-particle kunye nedayamitha encinci njenge-0.3 ye-microns ngelixa i-ULPA yokucoca i-particle encinci ukuya kwi-0.1 ye-microns ububanzi.

Izihluzi ze-HEPA ziveliswa ngemathiriyeli yelaphu ekumgangatho ophezulu kunye neenkqubo ezintsonkothileyo, ezinokubamba i-aerosol kunye ne-particulate kwi-99.997% okanye ukuphumelela okuphezulu kokuqokelela kwi-0.3 microns ububanzi. Oku kuqinisekisa ukuba izihluzi ze-HEPA zivala ngokufanelekileyo uninzi lwemibhobho ecolekileyo kunye nemibhobho ngokunjalo ne-aerosol yebhayoloji equlethe ibhaktiriya enetyhefu kunye neentsholongwane.

Kwimeko apho i-aerosol okanye i-particulate incinci kakhulu ukuba i-HEPA ihluze ukuba isuswe, i-ULPA yokucoca enokuthi ibambe i-aerosol kunye ne-particulate kwi-99.9995% okanye ephezulu yokuqokelela i-0.1 ye-diameter ye-microns, inokuba sisisombululo esifanelekileyo.

I-Xunling ductless fume hoods, iindawo zokusebenza kunye neendawo ezivaliweyo zixhotyiswe ngazo zonke ezi ntlobo zintathu zezihluzi, ukwenza inkqubo yokucoca edityanisiweyo yomthamo ophezulu kakhulu we-adsorption. Sicebisa ngamandla ukuba usixelele iimfuno zesicelo sakho ngokweenkcukacha phambi kokuba u-odole iiyunithi zethu. Iingcali zethu zesicelo ziya kucebisa ulungelelwaniso olufanelekileyo olusekwe kulwazi olunikezile ukuqinisekisa ukhuseleko lokugqibela, iziphumo ezigqwesileyo kunye nokusebenza okuphezulu.
